摘　　要：针对工业过程中经常遇到的一阶滞后系统,综合考虑了系统的响应时间、超调量、鲁棒性、噪声干扰等影响因素,提出了改进性能指标的智能PID参数整定算法。将改进的性能指标作为目标函数,通过布谷鸟搜索算法进行全局寻优,进而得到一组最优的PID参数。通过仿真分析,验证了该算法的有效性和优越性。Intelligent PID parameter tuning algorithms with improved performance index which taking the influence of system response time,over shoot,robustness and noise into consideration is proposed for first order delay system which is common in industrial process.A group of optimized PID parameters are calculated through the cuckoo optimization algorithm which takes improved performance index as the objective function.The effectiveness of the algorithm is verified by simulation.
